广东省高速公路拥堵时空特征探析及对策研究

Analysis and Countermeasures on the Temporal and Spatial Characteristics of Freeway Congestion in Guangdong

近年来,高速公路交通拥堵问题逐步凸显,尤其是节假日等高峰通行期间,局部路段拥堵已常态化。文中利用从百度实时路况平台采集的交通路况数据,从拥堵发生频次、持续时间以及排队长度3个维度深入分析高速公路拥堵的时空特征,阐述了广东省高速公路拥堵的规律,并相应分析了高速公路拥堵产生的原因及改善措施,为全省高速公路改扩建和路网优化提供有益建议。

In recent years,the problem of highway traffic congestion has become increasingly prominent.Especially during the peak period such as holidays,local road congestion has been a common phenomenon.By collecting the condition datas from the Internet,this paper analyses temporal and spatial characteristics of congestion from three dimensions including the highway congestion frequency,duration and queue length.Moreover,this paper analyses daily congestion characteristics of Guangdong provincial highway intensively.After putting forward the cause and improvement measures of provincial highway congestion,this paper gives some advice for the highway network optimization.
